Characteristic of cold rolling mills is their operation over an extremely large range of speeds reaching up to 2,000 m/min. That's why the main drive units often comprise changespeed gears with two transmission stages. This provides a correspondingly wide speed range. The spur gears and mill pinion gears are arranged in one housing.
